The OBDSTAR TCM-005 connects a 16-pin TCM connector on the vehicle side to a 15-pin DB15 connector on the device side. The cable is designed for Bosch TCM control units of the type DQ380 (0DE), DQ381 (0GC) and DQ500, where the connector sits directly on the transmission housing.
This concerns seven-speed wet-plate DSG transmissions used within the Volkswagen group in high-performance models and heavier-duty variants. This cable provides direct access to the transmission control module, bypassing the OBD2 port. This approach is intended for operations where standard OBD2 communication provides insufficient access, such as reading or reprogramming TCM data on MQB and MLB platform vehicles. The cable establishes a hardware-level connection; the actual operations depend on your programmer. Note the market distinction: the DQ380 (0DE) is primarily intended for the Chinese and Asian market and is rarely found in Europe. The model list below shows the transmission type and production years for each model.
KEY BENEFITS
IMPORTANT NOTES
Applications and capabilities
When used with OBDSTAR equipment, the cable supports the following operations on the Bosch transmission control module.
Control units you can access
- Bosch TCM (DQ380, DQ381, DQ500): Connected directly via the 16-pin connector on the transmission housing.
- No other control units: The cable accesses only the transmission control module, bypassing the OBD2 port.
What you can do
- Read TCM data: Retrieve current programming data from the control module via the direct 16-pin connection.
- Write TCM data: Rewrite or update software and calibration parameters via the DB15 interface.
- Identify transmission: Retrieve software version and hardware identification of the DQ380, DQ381 or DQ500.
- Perform hardware-level operations: Carry out procedures that are unavailable or limited through the standard OBD2 interface.
- Important: First confirm which gearbox type is fitted to the vehicle; DQ380, DQ381 and DQ500 units can be mixed within the same model designation.
Compatible vehicles and applications
What matters is the Bosch control unit — DQ380, DQ381 or DQ500 with 16-pin TCM connector — not the vehicle model. The vehicles listed below are equipped with these transmissions, with gearbox type specified per model. Only confirmed models and production years are included.
